Definitions
- This invention relates to sun visors, in particular to sun visors for motor vehicles.
- the spring leaf resists rotation of the visor panel so that the visor panel can be arranged at a desired angle relative to the shaft.
- a flat portion is frequently provided on the shaft so that the spring leaf positively retains the visor panel in a position corresponding to that which the panel occupies in a vehicle when not in use.
- a sun visor having a construction of this type is for example disclosed in British Patent Specification No. 1534282.
- a sun visor comprising a mounting bracket having a longitudinally extending shaft projecting therefrom, a visor panel mounted on the shaft for rotation about the longitudinal axis of the shaft, and a mounting clip connected to the visor panel for rotation therewith and including a spring leaf which exerts a radial force on the shaft which resists rotation of the visor panel on the shaft, characterised in that the spring leaf and the shaft include complementary inter-engaging radial formations which engage each- other to resist axial movement of the visor panel along the shaaft.
- the formations on the shaft and spring leaf thus enable the clip to perform the function of resisting both radial and axial movement of the visor panel relative to the shaft, thereby reducing the number of components in the sun visor, and facilitating its assembly.
- the formations comprise a groove and a ridge. This is most conveniently achieved by forming the groove oircumferentially on the shaft, and forming the ridge in the spring leaf, for example in a pressing operation.
- the clip is preferably formed as a one-piece pressing.
- the clip is preferably provided with one or more flanges having an aperture through which the shaft passes. These flanges can also be conveniently used to secure the clip to the visor panel by forming two arms in the or each flange, the panel being gripped between the two aims.
- a sun visor comprises a visor panel 1 of conventional construction which includes a peripheral wire frame 2 the ends of which are secured to a mounting block 3 of which may be a block of moulded plastics material (as shown) or a metal pressing.
- the block 3 includes two aligned sleeve portions 4, 5 through which a longitudinally extending shaft 6 of a mounting bracket 7 extend and which allow the visor panel 1 to rotate about the longitudinal axis 8 of the shaft 6.
- a mounting clip 10 positioned between the two sleeve portions 4, 5 also connects the visor panel to the shaft 6.
- the clip 10 comprises an integral pressing of spring steel and has a longitudinally extending back plate 11 one side of which is bent over to form a spring leaf 12.
- the inside surfaces of the back plate 11 and the leaf spring 12 are formed with a continuous transverse ridge 13.
- the side edges 14 of the leaf spring 12 are swept back, as illustrated in Figure 5.
- the back plate 11 has two longitudinally spaced end flanges 15, 15, ..
- Each flange includes an aperture 16, large enough to receive the shaft 6 and two transverely spaced arms 18, 19.
- Each arm 18, 19 has a flange 20, 21 on its inner side which extends in the longitudinal direction.
- the spring leaf 12 overlies the apertures 16, 16 and therefore engages the shaft 6 when the shaft is passed therethrough.
- the shaft 6 has a circumferential groove 22 complementary in shape to the ridge 13, and a longitudinal extending flat portion 24 at one end. The terminal end 25 of the shaft 6 is tapered.
- the clip 10 is connected to the block 3 by pushing the end flanges 15, 15 on to the block 3 so that the block 3 becomes firmly gripped between the inturned flanges 20, 21 on the inner sides of the arms 18, 19, and so that the apertures l6, 16 in the end flanges 15, 15 are aligned coaxially with the sleeve portions 4, 5 of the block 3.

- the engagement of the groove 22 and the ridge 13 resists further axial movement of the visor panel along the shaft 6 in either direction.
- the radial force exerted on the shaft 6 by the spring leaf 12 resists rotation of the visor panel on the shaft, and the engagement of the spring leaf 12 with the flat portion positively retains the panel in one rotational position relative to the shaft 6, corresponding t6 the position which the visor panel occupies when installed in a vehicle and not in use.

Abstract
Description
- This invention relates to sun visors, in particular to sun visors for motor vehicles.
- One known type of sun visor widely used in motor vehicles comprises a mounting bracket having a longitudinally extending shaft projecting therefrom, a visor panel mounted on the shaft for rotation about the longitudinal axis of the shaft, and a mounting clip connected to the visor panel for rotation therewith and including a spring leaf which exerts a radial force on the shaft. The spring leaf resists rotation of the visor panel so that the visor panel can be arranged at a desired angle relative to the shaft. A flat portion is frequently provided on the shaft so that the spring leaf positively retains the visor panel in a position corresponding to that which the panel occupies in a vehicle when not in use. A sun visor having a construction of this type is for example disclosed in British Patent Specification No. 1534282.
- In order to prevent the visor panel from moving axially relative to the shaft, it has been necessary to provide'a further clip which has added to the cost of the part and has increased the complexity of its construction.
- According to the present invention there is provided a sun visor comprising a mounting bracket having a longitudinally extending shaft projecting therefrom, a visor panel mounted on the shaft for rotation about the longitudinal axis of the shaft, and a mounting clip connected to the visor panel for rotation therewith and including a spring leaf which exerts a radial force on the shaft which resists rotation of the visor panel on the shaft, characterised in that the spring leaf and the shaft include complementary inter-engaging radial formations which engage each- other to resist axial movement of the visor panel along the shaaft.
- The formations on the shaft and spring leaf thus enable the clip to perform the function of resisting both radial and axial movement of the visor panel relative to the shaft, thereby reducing the number of components in the sun visor, and facilitating its assembly.
- Preferably, the formations comprise a groove and a ridge. This is most conveniently achieved by forming the groove oircumferentially on the shaft, and forming the ridge in the spring leaf, for example in a pressing operation. For simplicity, the clip is preferably formed as a one-piece pressing.
- In order to retain the spring leaf in engagement with the shaft, the clip is preferably provided with one or more flanges having an aperture through which the shaft passes. These flanges can also be conveniently used to secure the clip to the visor panel by forming two arms in the or each flange, the panel being gripped between the two aims.
- A preferred embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawings, in which:-
- Figure 1 is an elevation of part of a sun visor in accordance with the invention;
- Figure 2 is a similar view of a clip forming part of the sun visor of Figure 1;
- Figure 3 is an end view of the clip of Figure 2;
- Figure 4. is a side view, on a reduced scale, of a shaft forming part of the sun visor of Figure 1; and
- Figure 5 is a cross-section, taken along line V-V of Figure 3.
- Referring to the drawings, a sun visor comprises a visor panel 1 of conventional construction which includes a peripheral wire frame 2 the ends of which are secured to a mounting block 3 of which may be a block of moulded plastics material (as shown) or a metal pressing. The block 3 includes two aligned
sleeve portions 4, 5 through which a longitudinally extendingshaft 6 of amounting bracket 7 extend and which allow the visor panel 1 to rotate about thelongitudinal axis 8 of theshaft 6. Amounting clip 10 positioned between the twosleeve portions 4, 5 also connects the visor panel to theshaft 6. - Referring to Figures 2 and 3, the
clip 10 comprises an integral pressing of spring steel and has a longitudinally extendingback plate 11 one side of which is bent over to form aspring leaf 12. The inside surfaces of theback plate 11 and theleaf spring 12 are formed with a continuoustransverse ridge 13. Theside edges 14 of theleaf spring 12 are swept back, as illustrated in Figure 5. - The
back plate 11 has two longitudinally spacedend flanges aperture 16, large enough to receive theshaft 6 and two transverely spacedarms 18, 19. Eacharm 18, 19 has aflange spring leaf 12 overlies theapertures shaft 6 when the shaft is passed therethrough. Referring to Figure 4, theshaft 6 has acircumferential groove 22 complementary in shape to theridge 13, and a longitudinal extendingflat portion 24 at one end. Theterminal end 25 of theshaft 6 is tapered. - In order to assemble the sun visor, the
clip 10 is connected to the block 3 by pushing theend flanges flanges arms 18, 19, and so that the apertures l6, 16 in theend flanges sleeve portions 4, 5 of the block 3. Theshaft 6 is then pushed through thesleeve portions 4,5, theapertures spring leaf 12 radially outwardly until thetransverse ridge 13 in thespring leaf 12 of theclip 10 engages in thegroove 22 in theshaft 6. The insertion of theshaft 6 into theclip 10 is facilitated by itstapered end 25 and theinclined edges 14 of thespring leaf 12. - The engagement of the
groove 22 and theridge 13 resists further axial movement of the visor panel along theshaft 6 in either direction. The radial force exerted on theshaft 6 by thespring leaf 12 resists rotation of the visor panel on the shaft, and the engagement of thespring leaf 12 with the flat portion positively retains the panel in one rotational position relative to theshaft 6, corresponding t6 the position which the visor panel occupies when installed in a vehicle and not in use.
